I just threw the logs up, which contain the timings involved. I will try
to make graphs out of them, but the data is there. 

The logs contain:
* The time a given backend fetches a page, if that page is an even
multiple of 5k
* The duration of a scan
* The time the scan started
* The cache hit ratio as reported by log_executor_stats

Your right, I do need to summarize it and make it more visually
accessible.
